HeyGen moved #7 → #1 on the floor

What moved

#7 → #1

On the way it passed MakeRoll, Relume, Agent AFK, BuildAI, ChatGPT, Devin — their counted opens did not change; this listing's did.

The cause was one counted open of HeyGen's signed outbound link — a distinct visitor for that UTC day, signature checked, counted once on our server, bots and prefetches excluded.

The arithmetic

At that moment HeyGen had 4 counted opens in the 7-day window 2026-09-29 → 2026-10-05.

Counted means: one open per visitor per listing per UTC day, signature checked, our own traffic, bots and prefetches excluded before anything is added up, and paid placement kept on a separate surface that never feeds this number. Ranking rule organic-counted-opens v1, published in the methodology.

What cannot mint this page

Money. A sponsored click carries its origin on the event row and is filtered out of the floor in the query itself, so a paid seat can never produce a movement receipt. Excluded traffic cannot either — it changed no count. And the window quietly sliding overnight does not mint one: a receipt marks the counted open that moved a listing, not arithmetic doing its rounds.
